AIR-GUN.

SPECIFICATION forming part of Letters Patent No. 631,010, dated August 15, 1899.

Application filed December 24, 1897. Serial No. 663,434. (No model.)

To all whom it may concern.-

Be itknown that I, CLARENCE J. HAMILTON, a citizen of the United States, residing at Plymouth, county of Vayne, State of Michigan, have invented a certain new and useful Improvement in Air-Rifles; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference beinghad to the accompanying drawing, which forms a part of this specification.

My invention relates to air-guns; and its object is to provide improved means for looking the breakdown stock.

My invention is shown in the accompanyingdrawing, in which the figure is a side view showing parts of the barrel and stock, with the means for locking the stock.

In the drawings, A is the air-compression cylinder of the barrel, and to it is attached the bed-plate I3 and the bracket B.

C is the right-hand side plate of the breakdown stock, and opposite it is a similarlyformed but oppositely-arranged side plate, (not shown,) the two being pivoted to and over the bracket B on the trunnions b. The side plates are held to the stock D by the screw 1) and are provided at the upper and forward end with the trunnions orlugs 12 on which the link E is swiveled. This link is connected with the piston-rod in the usual manner.

F is a flat spring pivoted at the lower end on the trunnions b and rests at the upper end against the lugs 7), formed on the side plates. This spring is formed with an offset f at about its center, and the bracket B is provided with a cam b and a shoulder b over which the oifset portion of the spring rides and looks as the stock is swung into the closed position. This construction forms a frictionlock that can be overcome by applying sufficient force to the stock I am aware that the side plates and brackets have been used with a locking-lug; butI am not aware that the bracket has ever been used in combination with a locking-spring, as shown herein. By this construction the side plates are held rigid and are easily and cheaply made and assembled, while the expense of the spring-locking mechanism is reduced to the minimum,butis adapted to hold CLARENCE J. HAMILTON.
